A

The present invention is .an improvement on the device of the Congdonpatent, and is embodied in a leg-engaging member which is pivoted to thelever, instead of being rigidly attached thereto, so that said memberturns on the lever when the latter is moved downward, andthe jaws of themember exert a downward pull without such flexure of the leg as would beliable to break the latter.

Gf the accompanying drawings, forming a part of this specification-Figure 1 is a front elevation of a sinew extractor embodying myimprovement, the lever being fully lowered.

Figure 2 is a side elevation of the same.

Figure 3 is a side elevation, showing the lever fully raised.

Figure 4 is a .side elevation, showing the lever partly lowered.

Figure 5 is a front elevation, the parts being as shown by Figure 3.

Figure 6 is a perspective view, showing the leg-engaging memberseparately.

Figure 7 is a fragmentary view similar to a portion of Figure 3, showingthe legengaging member arranged to engage a relatively sfnall leg.

The same reference characters indicate the same parts in all of thefigures.

a designates a base adapted to be secured to a wall by screws orotherwise. b designates a foot-holder which is an arm or .appi'votc toears onthe base,

bracket projecting forward from the base .andv having a bifurcated end.rlhe space between the lingers of the forked end is made wide enough tosecure the bony part of the leg, asshown by Figures 3, 4 and 5, and theadjacent faces 01 edges of said fingers are beveled and ,provided with a.sharp edge on the upper side of the lower finger over which ltheleg maybeeasily'broken, as shown .by tllie Congdon patent.

cdesifgnates the hand lever connectedby the pivotal connection beingarranged as heretofore, below and at one sid-e of the. foot-h1older-yThe leg-engaging member in thefCjongdon patent is a claw,.a.rranged onand rigidly fatta'c'liedto fthe` lever 'c Vnear its pivot,V landprojectsllaterally from :that side of the lever adjacent thelfootholder, so that when the lever is v'fully raised onit's pivot,'theclaw engages the leg below the foot-holder, and then, as the lever ismoved downward, the ieshy part of the leg is drawn down, while the bonypart remains fixed in the footholder, so` that the sinews are extractedfrom the fleshy part of the leg, as described by the Congdon patent.

In carrying out my invention, I substitute for the claw fixed to thelever c', a leg-engaging member composed of a neck 12, bearing on theside of the lever c adjacent the foot-holder, a shank 13, projectingfrom one side of the neck through an orifice 14, in the lever, meanssuch as a nut 16, engaged with a threaded portion of the shank forretaining the shank in the orifice, and leg-engaging jaws 17, projectingside of the neck, and spaced apart by a legreceiving throat 18 (Figure6).

The shank 13 is preferably a headed bolt `extending' through an orificein the neck, and

through anorilice 14 in the lever, the head of the bolt bearing on oneside of the neck, and the nut bearing on the opposite side of the lever.The jaws are therefore free to turn on the lever during the downward.movement of the latter, so that they exert a downward pull on thefleshy portion of the leg, without flexing the bony portion, andtherefore without liability of breaking the latter. This liabilityexists when a leg-engaging member or claw rigidly secured to the leveris employed, as in the device of the Congdon patent.

The lever c may be provided with a plurality of orifices 14, located atdifferent disfrom the opposite tances from the pivot c2. Either orificeis adapted to receive the shank 13, so that the leg-engaging member maybe located at ditierent distances from the lever pivot 02, thus enablingthe extractor to be adjusted according to the size of the leg.

The jaws 17 are preferably more widely spaced apart at one end ot' thejaws than the other, best shown by Figure 6, so that by inverting theaws, they may be adapted to engage fleshy portions of the dilerentsizes.

The throat 18 between the jaws is preterably of such width that it isadapted to receive relatively large legs, such as those of turkeys. Toenable the jaws to engage relatively small legs, such as those ot hens,etc., I may provide the jaws with slots 20, which are open at the outerends of the jaws, the slots having leg-engaging edges collectivelyforming jaws adapted to engage a relatively small leg, the jaws beingturned, as shown by Figure 7.

I claim:

1. A sinew extractor comprising a base, a forwardly extended toot holderattached thereto having a forked end portion, and a hand lever connectedat its inner end portion to said base. by a pivot located below and atone side ot the 't'oot holder, the lever shank projecting from one sideof the base through an orilice in the lever, means retaining the shankin the orifice, and leg-engaging jaws projecting trom the opposite sideot' the base and spaced apart by a legreceiving throat, the t'oot holderand jaws being engageable with a toot and leg when the lever is in araised position, and operable by a downward movement ot the lever toseparate the leg` from the t'oot and extract he sinews, the jaws turningon the lever during said downward movement, so that they exert adownward pull without flexing the leg.

Q. A sinew extractor as specified by claim 1, the jaws being providedwith slots open at the outer ends ot the jaws, and having leg-engagingedges collectively torming jaws adapted to engage a relatively smallleg.

In testimony whereof I have aixed my signature.
